How to Convert Gigabytes to Exbibytes
To convert gigabytes (decimal/SI) to exbibytes (binary/IEC), multiply by 8.673617e-10. Decimal units use base 1,000, while binary units use base 1,024. Use our EiB → GB.
GB is a decimal (SI) unit—what storage manufacturers advertise. 1 GB = 1,000 of the smaller unit. See also: Gigabytes to Gibibytes.
EiB is a binary (IEC) unit—what operating systems often display. 1 EiB = 1,024 of the smaller unit. Use our Kibibits to Exbibytes converter.
1 GB = 8.673617e-10 EiB (using SI decimal standard) — or equivalently, 1 EiB = 1,152,921,505GB.
GB to EiB Conversion Formula
// Convert GB to EiB
EiB = GB × 8.673617e-10
// Reverse: Convert EiB to GB
GB = EiB × 1,152,921,505

What Is a Gigabyte?
A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use. Check out our Gigabits to Kibibytes calculator.
The gigabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our convert Petabits Per Second to Exabytes Per Second.
Common uses: Movies, video games, smartphone storage, USB drives, cloud storage plans Learn more: Gigabytes to Zettabytes conversion.
1 GB = 8 × 10⁹ bits = 1 × 10⁹ bytes.
The gigabyte can be abbreviated as GB; for example, 1 gigabyte can be written as 1 GB.
What Is a Exbibyte?
An exbibyte is 1,024 pebibytes or 2^60 bytes. Used for hyperscale storage in binary measurements. Try the EB to Exbibytes converter.
The exbibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Use our Exabytes to Eib calculator.
Common uses: Hyperscale data centers, global storage statistics in binary, cloud provider capacity Check out our convert GiB/s to Tebibits Per Second.
1 EiB = 9 × 10¹⁸ bits = 1 × 10¹⁸ bytes.
The exbibyte can be abbreviated as EiB; for example, 1 exbibyte can be written as 1 EiB.

SI Decimal vs Binary: Why Two Different Standards?
When converting gigabytes to exbibytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Why Does My Hard Drive Show Less Space Than Advertised?
This difference in standards explains the common "missing hard drive space" confusion.
Example: A "500 GB" Hard Drive
- Contains exactly: 500,000,000,000 bytes
- macOS (SI Decimal): Displays 500 GB (divides by 1,000³)
- Windows (Binary): Displays 465 GB (divides by 1,024³)
The Verdict: Same bytes, same drive—just different math. No space is actually missing.
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
💡 Storage Engineer Tip
The ~9.95% difference between binary and decimal units compounds at each level. A 1 TB drive shows as 931 GiB in Windows because of this standard mismatch—no space is actually lost.
